Detailed Description

The present invention will be further explained with reference to the following embodiments and accompanying drawings.

In the embodiments, as shown in FIGS. 2 to 4: the forming die for the Z-shaped bent terminal comprises a die frame consisting of an upper die plate 1, a lower die plate 2, a guide pillar 3 and a guide sleeve 4, wherein a bending die position 5 is arranged on the die frame, the bending die position 5 comprises a bending sliding block 501, a bending lower die 502 and a pushing block 503, the bending sliding block 501 is arranged on the upper die plate 1 and ascends and descends along with the bending die position, the bending lower die 502 is arranged on the lower die plate 2, a forming cavity of the Z-shaped bent terminal 01 is formed between the bending sliding block 501 and the bending lower die 502, and the pushing block 503 drives the bending sliding block 501 to horizontally slide through a contact inclined plane for secondary bending forming. The bending slider 501 of the present embodiment is disposed on the upper mold plate 1, can slide in two vertical or horizontal directions, and can lean against the lower bending mold 502 from two directions, so that two bending operations of the Z-shaped bending terminal 01 are realized by two movements of one bending slider 501, that is, auxiliary bending molding is realized by one mold position, so that the molding mold is compact, and the molding precision is also improved.

In the embodiments, as shown in FIGS. 2 to 4: the bending sliding block 501 and the pushing block 503 are both provided with a reset elastic piece 504. The elastic restoring element 504 of the present embodiment generally employs a compressed cylindrical spring, one end of which is in contact with the bending slider 501 and the pushing block 503, and the other end of which acts on the upper die plate 1, so as to achieve the restoration of the bending slider 501 and the pushing block 503.

In the embodiments, as shown in FIGS. 2 to 4: the upper template 1 is further provided with a power block 505, and the power block 505 drives the pushing block 503 to vertically slide through a contact inclined plane. The power block 505 of this embodiment is powered by a hydraulic cylinder, and the pushing direction is horizontal, so as to reduce the overall height of the mold.

In the example, as shown in fig. 4: the angle of the forming gap of the bending lower die 502 corresponding to the two bends of the Z-shaped bending terminal 01 is smaller than 90 °. The angle is shown as alpha in fig. 4 and is an angle smaller than 90 degrees, and a specific process angle is obtained by experience and experiments, mainly aiming at overcoming the rebound of a workpiece after 90-degree bending forming and keeping the accuracy of the bending angle of the Z-shaped bending terminal 01.
